I really appreciate all the hard work and love using Calibre with my ipad - But I am not happy with the new change that messes with categories. I have my library organized by type: Fiction, mystery, romance - not series. I put my series in grouping and album (disc number is series number). Is there a way to turn this new feature off?

The new updated iBooks sorts your bookshelf using albums - disks, so series stay together. Again can I turn your version of sorting off?
